1 Claim. (01. 240-81) This invention relates to lamps. In particular theinvention relates to adjustable lamps which may be raised or lowered tomeet the desire and convenience of the user.

It isan object of the invention to provide an adjustable lamp which ispractical, attractive and of simple construction. It is also an objectto provide an adjustable lamp in which the standard is composed oftelescoping tubular members.

Further objects and the advantages, novelty and utility of the inventiveidea will be brought out in the following specification, reference beinghad to the drawings, in which Figure 1 is a perspective view of acomplete lamp in its extended position.

Figure 2 is an elevation of the central telescoping member.

Figure 3 is an elevation in section of my complete lamp in its extended,upper position.

Figure 4 is a section of Figure 3, on the line Figure 5 is a section ofFigure 3, on the line As shown in Fig. 1, the lamp is provided with asuitable base member 6 in which is mounted a tubular element 1 withinwhich the tubular element 8 is telescoped, this last said element havingtelescoped therein the upper tubular element 9. As shown in Fig. 3, theelements I and 8 are rolled over at their upper edges as indicated at IIto afford a finish and also to retain the frictional members I2 and I3in place. A suitable cap I4 having an opening I5 is secured to the upperportion of the tubular element 9. From the above it will be seen thatthe assembled tubular telescoping elements form a hollow lamp standardwhich, as stated, is carried by the base member. Also carried by thebase member 6, by a suitable collar I4 centrally positioned within thehollow standard is a series of telescoping elements I5, I6, I! and I8which also are tubular in form. Suitable adjustment limiting slots I9,20 and 2| are cut in the telescoping elements I1, I6 and I5 and theelements I8, I1 and I6, carry pins 22, 23 and 24 which cooperate withsaid slots to limit the extent to which said telescoping elements may bemoved. A cap 25, secured to the top of element I8 carries a lamp socket26 in which may be secured an electric bulb 21. Also carried by the cap25, is a suitable holding means 28 for supporting the lamp shade 29. Asuitable electric cable 30, enters the base of the lamp and is looselycoiled about the inner tubular telescoping assembly and is connectedwith the lamp socket in a well known manner. Connected to the in--terior of the upper portion of the tubular mem-, ber I8 by the screw 3|is a metallic ribbon 32 of sulficient stillness to support thetelescopic assemblies in their adjusted position, the said ribbonpassing over the pin 33, the lower free end being stowed in arcoilwithin the space 34 provided for same in the base 6. From this and byreference to the drawings it will be seen that I provide an improvedlamp which may be raised or lowered through the feature of thetelescoping tubular assemblies and that when an adjustment is made itwill be retained until again manually changed.

Having illustrated and described a preferred embodiment of my inventionit is to be understood that changes and modifications may be resortedto, to meet special conditions, without departing form the spirit of theinvention as set forth in the claims. With further reference to thesteel tape means 32 which may be employed as described to retain thelamp in its. extended or up positions, it will be noted, see Fig. 3,that the base member 6 is preferably supported upon a plurality of studs6 by means of which it is connected to the foot-plate 4, the said studsaffording the space 34 within which a disc or circular member 4| may berotatably positioned. The lower portion of the steel tape 32 is twistedas at 43 so that the end thereof can be wound and secured upon the disc4 I. A knob 42 is carried by the disc 4| and is accessible through thespace 34 and may be engaged for making the partial turn of the disc 4Ithat is required to remove or provide slack in the tape 32 when loweringor raising the lamp. The disc M is rotatably mounted on the pivot pin44, set in the foot plate 4. 1

As has been pointed out, the frictional collars I2 and I3 may serve tohold the telescoping elements in adjusted positions, the lamp brackets28, which will not pass downwardly through the opening I5, serving toprevent the collapse of the inner, lamp carrying telescopic unit.Accordingly the use of the steel tape as a supporting means may or maynot be employed as desired.

It will also be apparent that the electric wire 30 may be arrangedinternally of the center telescoping unit instead of about same, ifdesired hence, by the same token one of the said telescopic assembliesmight be eliminated thus further simplifying the construction of thelamp.

I claim as my invention:

An adjustable lamp comprising a hollow outer scopic assembly including aplurality of telescopic elements, each of said telescopic elementshaving a vertically extending slot in the upper portion thereof and apin secured'thereto, the pin of one slot of the next lower telescopicelement, said pins being engaged within said slots limiting theuppermost and lowermost position of said lamp 1 while preventing rotarydisplacement of said telescopic elements, and means for simultaneouslyraising said inner tubular telescopic assembly and said outer tubulartelescopic assembly comprising a resilientband within said inner tubulartelescopic assembly having one telescopic element extending into the endof said band attached to the uppermost por tion of said inner tubulartelescopic assembly, a circular reel concentric with said inner base andsaid outer base rotatably secured within said outer base, said bandbeing secured at its lower end to said reel, and means accessiblethrough said outer base for rotating said reel, the rotation of saidreel serving to lengthen or shorten said band whereby said inner tubulartelescopic assembly and said outer tubular telescopic assembly isselectively raised and lowered.
